(cough) fag racing* I wouldnt drift in the same set up I have adjustable shocks, and different sets of tires for that. All im asking is what is the important bushings needed for nuteral handling. layoff. --------------------------------------------------------------------------------

Secondly, bushings don't change the rotational charactersitics of a car, unless there is a problem with them. Stiffer bushings just comply less so that suspension movements are more precisely controlled and allow the suspension components to respond quicker.
Lastly, I've never heard of a drift autoX set-up. I would think most drifters would like more room than an average autoX course allows.
If you talking about bushings for autocross and drifting, basically what they are going to do is make the car feel more "stable" and responsive. First thing you should do is the rear subframe bushings (Whiteline for example. I got mine from pdm). After I installed them they made a noticable difference in how the car feels, and helps the rear end stay in line. I also just installed the nismo power brace w/ new TC rods w/ poly bushings (you can also get the heim joint ones for adjustable caster and even less compliance (harsher ride)). This made a difference as well as it made the car's turn in is more responsive, and feels like less understeer. I will be looking into getting polyurethane steering rack mount bushings (installed these on my 78 280z, and they made a world of a difference), although I haven't found them directly available for a 240sx. I've heard that the ones for a Z32 should work, so Ill order them and take a look. You can order Nismo ones, which are harder rubber then the OEM ones, from the current Nissan Motorsports catalog from your Nissan dealer. As for the rear control arms and bushings, I don't have experience with these yet, although I plan on getting cusco components. These will, from what I've read, increase ride noise/harshness, but I can live with that for the more solid ride. And to get to the point I guess, the bushings themselves don't have alot to do with how your car rotates themselves as C-Kwik mentioned, but they are supporting mods for the things that will; such as adjustable swaybars, what your spring rates are, if you have adjustable bound/rebound, and if you get adjustable rear toe control links, you can add some toe-out for some more oversteer.
But all of these things will need to be done eventually IMO, and your not wasting money by slowly putting these components on, and it makes the car more fun to drive.
Hope that helps a little, and forgive if I didn't paragraph or put my sentences together correctly. :icesangel
